摘要

Kwanar-Are reservoir is located along Katsina - Kano Federal road (Northern Nigeria). It has been used for over two decades as a source of water for irrigation and infrastructural development in Kasina city and environs. This study is intended to determine the quality of water in the reservoir to establish its suitability or otherwise for use in mixing concrete. The investigation is very necessary having in mind that the irrigarion activities take place on substantial portion within the reservoir for which the long term application of fertilizer and pesticides might have negetive impact on it. Samples of water were collected and examined. Parameters such as pH value, chlorides, sulphates, alkalies, and solids as well as organic impurities were determined which essentially affect the setting time of cement, strength, durability and other properties of the concrete. Result obtained shows the tested parameters in negligible quantities. Metals are in trace quantities also. The determined compressive strength of concrete cubes of the diamension 150×150×150 made from water in the reservoir for 7 and 28 days after curing are within normal range. Frequent monitoring of the reservoir is necessary by all stake holders especially the Regulatory Bodies of water resources in Katsina state.
